Fixed-field alternating gradient ones are employed in anti-cancer proton therapy. Early examples used sulfur hexafluoride to apply a static voltage of around thirty megavolts, while oscillating voltages are employed in more modern linear examples. One type of this structure 
Fixed-field alternating gradient ones are employed in anti-cancer proton therapy. Early examples used sulfur hexafluoride to apply a static voltage of around thirty megavolts, while oscillating voltages are employed in more modern linear examples. One type of this structure employs a pair of D-shaped plates in conjunction with a single powerful (*) magnet. Mundane examples include cathode ray tubes, and many of these devices benefit from storage rings, particularly those that collide two beams. For 10 points, name these machines, which include the Tevatron and the Large Hadron Collider.
